Correct Answer

A. (15)

Step 1

Concept

The union is (14+9+17=40), so outside is (55-40=15). The outside region is the complement of the union.

Step 2

Why this answer is correct

The correct answer is A. (15). The union is (14+9+17=40), so outside is (55-40=15). The outside region is the complement of the union.

Step 3

Exam Tip

संघ (14+9+17=40) है, इसलिए बाहर (55-40=15)। बाहर का क्षेत्र संघ का पूरक होता है।
